Counting the cars that go across the Brooklyn and Golden Gate Bridges every day doesn't exactly sound like fun. But when we're talking about the Multi-State ZEV Action Plan that eight US states are using to boost zero-emission vehicle adoption, though, we can think of it as a positive thing. That's because a quarter million vehicles cross those iconic bridges every day, and that's how many zero-emission vehicles have been sold in the US.

Efficiency equals performance, especially in the case of Formula 1 racing. The Mercedes AMC Petronas team points to several key efficiency technologies it uses to get the most out of its cars. And if their utter dominance so far this season is testament to this relationship, perhaps we should pay attention. Mercedes highlights hybrid tech, turbocharging, aerodynamics, lightweight construction, tribology (both in making internal components and lubricants more slippery) and simulation as crucial t

Spinal Tap waxed poetic about the value of turning things up to 11. So it's a good thing that that's the number of steps a coterie of eight states (led by California) will take to reach a goal of having 3.3 million zero-emission vehicles (ZEV) on their roads by 2025. Now let's rock.

A Vermont woman lost control of her car along Route 5A, crashed into a tree and lost her husband in the ensuing accident. It all seemed like a terrible tragedy. In time, it was revealed to be a terrible crime.

EPA standards govern vehicle emissions such as NOx and hydrocarbons. They are byproducts of combustion that can be balanced with engine tuning, such as ignition timing and fuel delivery. They can also be reduced through devices such as catalytic converters. Catalytic converters cause a chemical reaction that converts carbon monoxide into carbon dioxide and hydrocarbons into carbon dioxide and water. However, earlier this year the EPA won a Supreme Court ruling adding carbon dioxide to the list o

General Motors and the former DaimlerChrysler have been handed a disappointment in a Boston district court. At issue was Vermont's adoption of California's carbon dioxide standard, which requires cars and light trucks to reduce their emissions of the greenhouse gas by 30 percent. GM and DCX brought suit against the state of Vermont, claiming that Federal law was being usurped by states demanding their own emissions standards. Furthermore, the automakers say they couldn't meet the standard, and w

Depending on your viewpoint, California is trying to make the world better for people everywhere, or trying to kill all the joy of automobiles and perhaps the entire domestic auto industry. In 2004, California adopted a requirement declaring that automakers reduce their fleets' CO2 emissions from September 2008, which would begin the 2009 model year. The first year's cut would be 1-2%, culminating in 2016 with a 24-36% reduction from the amount of 2002 CO2 levels. Eleven states have followed Cal

If you're at a loss to understand the complexities of the carbon dioxide battle waging in the courts between automakers and some states, check out an in-depth 2-part story written by Tim Johnson of the Burlington Free Press (Article 1, Article 2). Vermont is one of the states involved in the legal action that stretches across the country as some states want to impose restrictions on the output of greenhouse gasses.
